[This corrects the article on p. 562 in vol. 9, PMID 30949410.].To evaluate the effect of post-mastectomy radiation therapy (PMRT) stratified by clinical tumor (T) or nodal (N) staging and determine predictors of overall survival (OS), locoregional recurrence (LRR), distant metastasis, and disease-free survival (DFS) in patients with breast cancer who received neoadjuvant chemotherapy (NACT) and total mastectomy (TM), we enrolled patients who received a diagnosis of breast invasive ductal carcinoma who received NACT followed by TM. Cox regression analysis was employed to calculate hazard ratios (HRs) and confidence intervals (CIs). Univariate and multivariate Cox regression analyses indicated that non-PMRT, Charlson comorbidity index ? 2, advanced clinical T or N stage, pathologic partial response, pathologic stationary disease, or pathologic progression disease were poor prognostic factors for OS. Well-differentiated tumor grade, pathologic complete response, and positive hormone receptors were better independent prognostic factors for OS. Adjusted HRs derived from PMRT for breast cancer after NACT and TM were 0.69 (0.53-0.89) and 0.74 (0.59-0.93) in clinical T3 and T4, respectively. aHRs derived from PMRT for breast cancer after NACT and TM were 0.67 (0.45-0.99), 0.75 (0.62-0.92), and 0.77 (0.60-0.98) in clinical N0, N1, N2-3, respectively. The aHRs (95% CI) of the PMRT group to the non-PMRT group for LRR-free survival and DFS were improved significantly. Our study indicated that PMRT significantly improved OS in clinical T3N0-T4N3 and for LRR-free survival and DFS in clinical T2N0-T4N3 from those of non-PMRT patients regardless of pathologic response and other predictors.In certain difficult cases involving tumors unclear in B-mode ultrasound or tumors in a high-risk location, image-guided liver tumor thermal ablation was previously contraindicated. The aim of this retrospective study was to investigate the value of intra-procedural ultrasound fusion imaging in improving the therapeutic effect and safety of liver tumor ablation in difficult cases. A total of 502 patients (441 males and 61 females, aged 52 ± 11 years) with 805 liver tumors (16 ± 6 mm; range, 4-29 mm) who underwent thermal ablation with intra-procedural fusion imaging from October 2010 to June 2018 in our hospital were enrolled. Fusion imaging was employed for targeting, puncture guidance and immediate evaluation of the therapeutic response. Contrast-enhanced computed tomography (CT)/magnetic resonance imaging (MRI) was performed one month after ablation and every 3~6 months in the follow-up period. 511 and 294 liver tumors were in classified in the difficult case group and the non-difficult case group, respectively. The technical efficacy rate was 99.4% (800/805), and no difference was found between the two groups (P=0.658). https://www.selleckchem.com/products/ml210.html in the local tumor progression rate was found between the difficult case group (1 year 3.2%; 3 years 7.6%; 5 years 7.6%) and non-difficult case group (1 year 2.1%; 3 years 5.5%; 5 years 11.6%) (P=0.874). The major complication rate was 1.8% (11/608). Injury to adjacent organs occurred in only 1 patient who sustained a bile duct injury. We conclude that intra-procedural fusion imaging can improve the therapeutic efficacy and safety of thermal ablation in difficult cases and may expand the indications for thermal ablation.Vitamin D has a potential anticarcinogenic role, possibly through regulation of cell proliferation and differentiation, stimulation of apoptosis, immune modulation and regulation of estrogen receptor levels. Because breast cancer (BC) risk varies among individuals exposed to similar risk factors, we hypothesize that genetic variants in the vitamin D pathway genes are associated with BC risk. To test this hypothesis, we performed a larger meta-analysis using 14 published GWAS datasets in the Discovery, Biology, and Risk of Inherited Variants in Breast Cancer (DRIVE) Study. We assessed associations between 2,994 (237 genotyped in the DRIVE study and 2,757 imputed from the 1000 Genomes Project) single nucleotide polymorphisms (SNPs) in 33 vitamin D pathway genes and BC risk. In unconditional logistic regression analysis, we found 11 noteworthy SNPs to be associated with BC risk after multiple comparison correction by the Bayesian false-discovery probability method (T) to be associated with BC risk (P = 0.0014, 0.0020 and 0.0022, respectively). Additional expression quantitative trait loci analysis revealed that the rs73276407 A allele, in a high LD with the rs1047920 T allele, was associated with decreased SNAI1 mRNA expression levels, while the rs11826 T allele was significantly associated with elevated AMDHD1 mRNA expression levels. Once replicated by other investigators and additional mechanistic studies, these genetic variants may serve as new biomarkers for susceptibility to BC.Energy metabolism in cancer cells is reprogrammed to meet the energy demands for cell proliferation under strict environments. In addition to the specifically activated metabolism of cancer, including the Warburg effect and glutaminolysis, most amino acids (AAs) are utilized for gluconeogenesis. Significant increases in AAs and energy metabolites in the tumor region occur in gastric and colon cancers. However, a different AA-related energy metabolism may exist in lung cancer because of the abundant blood supply to lung tissue. This study compared the profiles of AAs and their related metabolites in energy metabolism, analyzed by an HPLC-MS/MS system, between tissues from nontumor and tumor regions collected from 14 patients with non-small cell lung cancer (NSCLC). In the energic metabolism precursor categories, the glucogenic AAs, which included the pyruvate precursors (Ser, Gly, Thr, Ala, and Trp), the α-ketoglutarate precursors (Glu, Gln, and Pro) and the succinyl-CoA precursors (Val, Ile, and Met) were significantly increased in the tumor region compared to in the nontumor region. However, no significant differences existed between the two regions in the ketogenic AAs (Leu, Lys, and Tyr). These differences were not observed between the subgroups with and without diabetes mellitus in the two regions. #link# The metabolites on the left-hand side of the TCA cycle were significantly higher in the tumor region, but no differences in metabolites in the right-hand side. The mRNA expressions of major AA transporters and cancer proliferation factors were also significantly increased in the tumor region, compared to these in their counterparts. In lung cancer, glucogenic AAs that are actively transported from circulating fluids would be predominantly utilized for gluconeogenesis, with and without diabetes mellitus. The characteristics of the AA-related metabolism would be associated with tissue-specific cell proliferation in patients with NSCLC.
